well Piye, formerly called Piankhi, (flourished 8th century bce), king of Cush (or Kush, in the Sudan) from about 750 to about 719 bce. He invaded Egypt from the south and ended the petty kingdoms of the 23rd dynasty (c. 823– c. 732 bce) in Lower Egypt.
Perhaps one of his greatest accomplishments was conquering Nubia, a region near the Valley of the Kings (where most pharaohs were buried) that became annexed to Egypt. Thutmose III's reign made Egypt wealthier and more widespread than it had been for about a thousand years.
